for a rather simple 2-projector video installation, I wrote a patch to blend the edges. Up to now just by using a grayscale matrix for the alpha channel that I send to an jit.gl.videoplane.
Now, what's the actual problem: I am worried, that I will need some gamma correction in the blending area as up to now I am just adding pixel values in this area. Does anyone have some experiences with edge blending (because I don't) in Jitter and how to do the gamma correction best? I know about the jit.displays abilities and was thinking about using the "coords"-message to define the area of gamma adjustment. I won't be able to try around much with the two projectors running, so I have to prepare everything beforehand and want to get sure that I am on the right track - so thanks a lot for any advice.
